quickly ejected and loaded shells trans,

ferred from the magazine to the rifle barrel.

The main ohject of the present invention is the provision of a pumping mechanism controlled and operated by the usual l'ore arm, which, for the purposes oi theinvention, is slidahly mounted on the magazine, the initial movement of the forearm unloclc ing the hreech-bolt and the subsequent movement oil? said arm moving the l. reech holt longitudinally to eject the discharged shell, the opposing movement of the forearm returning the breech-bolt to closed position and during such movement elevating a loaded shell from the magazine into the path of the lnccch-lmlt.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which:

F l) is a perspective view of the carrier. Fig. 10 is hrolien horizontal section taken through the carrier-housing. Fig. 11 is a perspective ol' the actuating lever. F is a section on line 12*l2 ol' Fig. 4.

Referring particularly to the accompanyis a broken side elevation of a gun ing drawings, my improved magazine rifle includes a stock 1, barrel 2, and magazine 3,

"all parts being of the usual type and con struction, the cartridges being led in the magazine through the usual trap openin 4 in tie wall of the chamber 5. H l

A brooch-bolt 6 is slidably mounted. 1n the chamber, being arranged in the upper portion thereof and having one'sidc edge adapted to close a discharge opening 7 in the chamber. The breech-bolt, which is more par,

ticularly illustrated in Fig. 8 of the drawings,

Zis of rectangular shape in cross section and iappr-o-Xunately ol solid construction, being formed on its upper edge with a tongue 8 to lit in a groove 9 in the upper wall of the chamber. The forward end of the breechbolt is formed to provide an. abutment 10 and is provided with tl o usual spring extracting linger 11 for withdrawing the discharged shell in the opening movement of the bolt, it being uiulorstood that the shell rests against the abutment 10 when in firing position, as clearly shown in Fig. 2. A breech-bolt 1S longitudin ally cored for the reception of the .liringpin 12, which, as has been heretofore constructed, is preferably-made up in a tiring section 13 and a driving section 14 mounted in alinement in the core of the bolt with the hammer and the former to discharge the The breech-bolt, as more clearly shown 111 Fig. 3, is formed near lts rear end;

cartridge.

latter designed to receive the im iact of the with a recess 15 opening through the lower 'surlace of the bolt so arranged that the driv- 1mg section 14 oi the hrmg pm may be tilted in the bore of the bolt so as to dispose said,

the bolt, while the relatively inner side of the bolt is formed with a longitudinally extendmg groove or channel 18 to permit movement ol and insure operation of the ejecting member 19 as is usual in this type of gun, it being understood that the ejecting member is mounted in the side wall of the chamber 5 and operates to dollect the discharged shell as the latter is drawn rearwardly by the breech-bolt so as to cause the shell to be projected through the opening 7 of the chamber.

Pivotally mounted in the chamber 5 is what I term a carrier 20, which is illustrated in detail in Fig. 9. The carrier comprises an elongated body 21 from the rear end of which projects an angularly related ear 22 formed with an opening 23 for the reception of the pivot pin. The carrier 20 is of such length that when in lowered or inoperative position the forward end of the body terminates immediately in rear of the rear end of the magazine, and said forward end of the body is formed on its upper surface with a rounded depression 24 and an car 25 projecting upwardly from the edge of said depression, whereby to receive and guide the cartridge as hereinafter described. The lower edge of the carrier is formed at a point slightly rearward of its center with a triangular projection 26, which depends from said lower edge and has its side or operative edges 27 slightly curved, as shown. From the forward edge for a portion of its length the body of the carrier is of greater width than the remainder, as at 28, which section of increased width terminates in an abrupt shoulder 29, the edge of which inclines upwardly and forwardly, as shown. The upper surface of the body is formed with a rounded depression 30, which at its forward end is coincident with the depression 24 and toward the rear inclines from the longitudinal median line of the body toward the side edge, so that the cartridge receiving depression is, as an entirety, inclined with respect to the longitudinal line of the carrier so that in the movement of the cartridge lengthwise said depression it will be deflected to one side of the carrier. Secured on the upper edge of the body immediately in advance of the rear car 22 is a housing 31, one wall 32 of which is free and pivotally supported in the body at 33, being formed adjacent the pivot with a lateral projection 34 designed when the wall 32 is in normal position or in alinement with the ad' .cent side edge of the body to engage t e opposing side wall of the housing and limit further outward movement of the wall 32. A spring 35 is arranged within the housing to normally maintain said wall 32 at its limit of outward movement, and said wall on its outer side is formed with lateral proj ections 36 and 37 arranged respectively adjacent the ends of the wall. The projection 36 is, on that edge adjacent the projection 37, downwardly and forwardly curved, as shown, while the adjacent edge of the projection 37 is oppositely curved the rear edge of the projection 37 is forwardly and rear wardly curved at 38, for a purpose which will presently appear.

An actuating lever 39 is pivotally mounted in cars 40 extending below the chamber, said lever being plain on one face throughout its length and formed on the opposing face with a cam dog 41, having its relatively upper edge 42 of cam formation, as clearly shown in Fig. 3. The lever is of such length that when in place the upper end thereof will extend into the opening 17 in the breech-bolt, so that in the reciprocal movement of said bolt the lever is operated. The relatively forward edge of the lever immediately below that portion engaging the breech-bolt is formed with a notch. 43 arranged to cooperate with the cartridge, as will presently appear.

A locking key 44 is arranged in the chamber to lock the breech-bolt in closed position, said key comprising a plate 45 forming the base of the key and uprights 4647 rising from the plate in spaced relation, the upper ends of the bolt uprights 46 and 47 being designed when the breech-bolt is in closed position to project into the opening 15 in said bolt, and a spring 48 is arranged within the chamber, encircling pins carried by the bot tom wall of the chamber and depending from the lower surface of the plate 45 to normally maintain the key in looking position. The

upright 47 is of greater thickness than the.

upright 46, and the relatively inner edge thereof is formed at the upper portion with a rounded depression 49, which, when the key is in elevated or looking position, is designed to engage the driving section 14 of the firing pin and maintain it in operative position, that is in alinement with the firing section 13 of the pin, as will be clearly apparent from Fig. 2 of the drawings. The uprights 4647 of the locking key are spaced apart to permit passage therebetween of the ear 22 of the carrier, so that the key in effect straddles the carrier in operation. The relatively outer surface of the upright 47 is cut out to provide a squared shoulder 50 and the forward edge of the plate 45, which is projected in advance of the forward edges of the uprights, is inclined forwardly and downwardly relative to the uprights, as at 50, terminating at its highest point in coincidence with the shoulder 50, for a purpose which will presently appear.

The forearm 51 is, for the purpose of this invention, slidably mounted upon the magazine 3 of the gun, and from said forearm there is rearwardly extended a strip or operating arm 52, which has its rear portion 53 offset vertically and formed at an appropriate point with a slot 54 to permit the passage therethrough of a screw 55 designed to take into a threaded opening in the breech-bolt. A setting bar 55 extends rearwardly from the forearm, preferably from the side opposite the operating arm, said setting arm extending through an opening in the forward portion of the chamber and extending lengthwise within the same, as clearly shown in Fig. 6. At the rear portion the setting arm is provided with an inclined or cam edge 57, which is designed to cooperate with the inclined portion 50 and shoulder 50 of the looking key, the parts being so arranged that in the rearward movement of the forearm, the setting arm will operate to depress the locking key and release the breech-bolt.

The forward edge of the carrier 20 is provided with a depending lip 58, for a purpose which will presently appear, and it is to be understood, of course, that the iiroarm is provided with the usual hammer 59 and trigger (30 for cooperation and actuation in the usual manner.

The lower surface of the breech-bolt is formed with a depending projection 61 designed in operation of the breech-bolt to engage a hammer, and in the movement of said hreech-belt to open position so actuate the hammer as to set or cook the same Within the influence of the trigger.

The various parts described are, when in normal position within the gun and the breech-bolt closed, relatively disposed as l'ol lows: The hrcech-bolt is at its limit of forward position in which the cartridge with its rim engaged by the linger 11 is held in the barrel of the gun, and the locking key elc vated so that the sections ol' the iiring pin are in alineinent to transfer the impact of the hammer to the cartridge. The carrier with its ear between the uprights oi the locking hey is extended in the forward position with the lip 58 resting on the bottom of the chamher and the cartridge groove in alinen'ient with the lower portion of the magazine wall, so that a cartridge could, so far as the carrier was concerned, be discharged from the magazine onto the carrier by the spring pressed piston within the magazine. The actuating lever 39, however, is in the forward position, that inclined 'l'oruardly with respect to its pivotal connection. in this position said lever has its upper end in the opening 17 in the l)i7iil.)l)lt and its forward edge bearing against the inclined shoulder 29 of the carrier. in this position the size and arrangement ol the parts is such that the notch 13 in the forward edge of the actuating lever will l'orm a receiving notch to limit the rearward movement of the cartridge in the magazine, so that said cartridge is but partially projected onto the carrier, all as clearly shown in Fig.

Assuming now the iirearm to have been discharged and it being desired to eject the :lircd shell and recharge the barrel, the operation is as follows: The arm 51 is moved in the rearward direction that is toward the chamber Owing to the slot and pin connection between the operating arm 52 and the breech-bolt, the initial rearward movement oi the lore-arm is without ell'ect upon said. bolt, while such initial movement through the medium ol the cam portion 57 01' the setting arm 56 operates to .vithdraw the locking lcey l'rom engagement with the belt.

The .l'urther rearward movement of the lorearm tends to move the breech-bolt in the rearward direction, or toward the open position. This movement causes a similar rearwardmovement ol' the upper end of the actuating lever 39. The initial effect of the rearward movement ol said lever is to permit the cartridge normally overlying the carrier to follow said lever until the cartridge rests wholly on the carrier. During the rearward movement ol' the lever as described and just prior to the time at which the cartridge is wholly discharged from the magazine onto the carrier, the cam surface 42 oi the dog 51 engages the forward edge 27 of the projection 26 depending l'roni the carrier and slightly elevates the forward end 01' the carrier. This movement oi the carrier will, of course, raise the forward end thereol' above or out ol alinement with the lower surface ol' the magazines i'orniing a stop to prevent the discharge of any other cartridge from the magazine. The complete rearward movement oi the upper end of the lever is without further cll'ect upon the carrier except that as said lever continues its rearward movement it will engage the forward projection on the carrier, forcing the l'orwariil end of the wall inwardly to permit the lever to pass the projection. In the final position ol the parts, therefore, when the breechbolt is open the actuating lever rests between the projections 36 and 3'] on the carrier, a loaded cartridge is resting upon the carrier and the latter is in position to form a stop to prevent egress ol' the next succeeding cartridge lrom the magazine. It is, of course, to be understood that, as is usual in this type or" gun, the projection 61 of the breech-bolt will, in the opening movement ol' the latter, actuate the hammer to cook the gun, while the ejector 1. 9 will force the discharged shell 'lrom the breech-bolt and direct the same through an opening 7 provided as the breech-bolt moves rearwardly. in the forward movement of the l'orearm the breech-bolt is drawn in the forward direction, thereby again rocking the upper end ol the actuating lever 'l'orwardly. As said lever is between the stops 3637 of the carrier, the movement ol' the lever will gradually elevate the lorward end ol' the carrier until the forward end 01' the cartridge resting on the carrier is in line with the barrel. As the cartridge groove 30 in the carrier inclines, the rear end of the cartridge will be ollset from the longitudinal line oi the carrier and by the elevation of the latter the rear end ol the cartridge will be disposed in position to be engaged by the forward end of the breech-bolt, so that the 'l'orv. l movement of the latter will l'orce the cartridge into the barrel. The elevating influence oi the actuating lever on the carrier will continue until said lever has reached a point beyond which it cannot force the carrier upward,

owing to the different pivotal supports of the parts. When this position has been reached the further forward movement of the lever will engage the projection 36 with such pressure as to again force inward the wall 32 and free the lever from further connection with the carrier. It is at this time or just prior to this time that the breech-bolt has engaged the cartridge and forced the same part way at least into the barrel, so that immediately the carrier is released. from the lever said carrier is free to gravitate to normal position, though this action is assured by the fact that when. the lever is in normal position it will engage the shoulder 29 of the carrier and force the latter if necessary to a proper position.

The thickness or vertical dimension of the forward end of the body of the carrier coupled with the height of the lip 58 are of such aggregate vertical dimensions asto prevent a complete unclosing of the magazine mouth during the operative movement of the carrier, so that at any time during the actuation of the mechanism, the forward end of the carrier serves to prevent the escape of the next succeeding cartridge from the magazine. Owing to the few parts and the fact that no correlation requiring time in successive actuation is necessary it will be obvious that the action of the improved pumping mechanism may be as rapid as desired, and that the discharged shell is ejected with certainty and the fresh shell disposed in discharging position without loss of time. A rifle may be emptied in considerably less time than the usual lever action and the present improvements can be readily applied to any form of lever action.

Having thus described the invention what is claimed as new, is

1. A magazine firearm including a magazine and a barrel, a cartridge carrier operating between the magazine and barrel, a breech-bolt, means for operating the breechbolt in both directions, a lever mounted within the firearm and engaging the breechbolt, means carried by the lever to engage and elevate the carrier during movement of the breech-bolt in one direction, and means operated by the lever during movement of the breech bolt in the opposite direction to further elevate the carrier.
